Turbo/Supercharger Intercooler Temperature Sensor Circuit

on 2015 Jeep Cherokee 3.2L V6 · AWD

What this code means

The charge air cooler (intercooler) temperature sensor is reporting values outside the expected range. The PCM uses this data to optimize boost and timing.

Symptoms

  • Check Engine Light
  • Reduced power in hot conditions
  • Excessive timing retard
  • Poor performance on hot days
  • Inconsistent boost levels

Common causes

  • Faulty intercooler temperature sensor
  • Corroded sensor connector
  • Damaged wiring
  • Clogged intercooler fins
  • Intercooler leak reducing cooling

Diagnostic steps

  1. Read intercooler temp PID and compare to ambient
  2. Test sensor resistance vs temperature chart
  3. Inspect sensor connector for corrosion
  4. Check intercooler for external blockage
  5. Pressure test intercooler for leaks

Repair notes

Replace intercooler temperature sensor. Clean intercooler fins if clogged. Repair any intercooler leaks found.

⚠ STILL BEHIND THE PAYWALL
The 2015 Jeep Cherokee repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
